Abstract

The present invention relates to an improved telescopic toilet paper roll holder which substantially deadens the sound of a roll of toilet paper while being rotated; self-aligns and snuggly holds either a uniform or misshaped roll of toilet paper in place, preventing axial play and mutilation of the paper edges; produces a slight drag while being rotated, preventing paper runaway. This improved holder is comprised of a foamed polymer tube encompassing two hollow cylinders having slightly different diameters, nested together through their inside ends and supporting felt covered pintles on their outside ends, with a helical compression spring inside the larger cylinder urging both cylinders to extend axially; cylinders are provided with a protuberant to keep them from coming apart.

BACKGROUND OF THE INVENTION

Recessed toilet paper roll wall receptacles have assumed an almost universal appearance and simple structure, with opposed trunnions containing bearing holes to accommodate telescopic holders of a standard roll of toilet paper approximately 4.5 inches long by 4.5 inches in diameter with a center hole core of approximately 1.5 inches. These receptacles are only partially recessed in a wall so that the trunnion bearing holes are located on the room side of a wall surface to simplify inserting a holder containing a standard roll of toilet paper.

Telescopic toilet paper holders have also assumed almost universal appearance and simple structure to accommodate a standard roll of toilet paper. They are comprised of two hollow cylinder members having slightly different diameters, nested together through their open ends and partially closed on their outside ends to support pintles. They are approximately 1 inch in diameter and have the capability to expand from approximately 4.5 inches to 5.75 inches. A helical compression spring inside one of the cylinders urges both cylinders to extend axially. The cylinder members are provided with a protuberant to keep them from coming apart.

The problem with paper roll holders of the foregoing type us that they loosely journal and support a roll of toilet paper of the present era (made with relatively thin soft cardboard cores) because the outside diameter of the holder is approximately 50% smaller than the inside diameter of the core of a roll of toilet paper. Because of these impediments: it is a common experience to hear excessive noise when a misshaped or damaged roll of toilet paper is being unwound, resulting in mutilation of paper edges and paper runaway due to axial play; when someone pulls paper from a roll after fifty percent or more of a misshapen paper roll has been dispensed the roll is subject to paper runaway, resulting in a fast and noisy clattering sound of the paper core rotating around the holder, while the holder itself rotates very slowly on its pintles or remains fixed.

BRIEF SUMMARY OF THE INVENTION

A toilet paper holder comprised of two telescoped hollow cylinder members encircled by a flexible foamed polymer tube; each cylinder member having an inside and outside end. The first cylinder member is affixed to the foamed polymer tube. Said tube extends from the affixed encircled first cylinder member in the manner of a cantilever to the un-affixed encircled second cylinder member; the second cylinder member slides through the bore of the foamed polymer tube and into the bore of the first cylinder member. The outside ends of both cylinder members are provided with cylindrical pintles. The circumferential surface of the pintles are encircled with felt strips and felt disks are attached to the ends of the pintles. A helical compression spring inside the first cylinder member urges both cylinder members to extend axially.

The outside diameter of the flexible foamed polymer tube which encompasses the telescopic cylinder members, is slightly larger than the inside diameter of a standard toilet paper core so that a roll of paper can be held in a snug position on the holder by the expansive force of the foamed polymer member. This diameter difference does not cause any undue effort in loading a roll of paper, which can be slightly tilted on the holder because of the pliability of the foamed polymer.

The resilient foamed polymer encircled telescoped members and felt surfaced pintle members, substantially deadens the sound of a roll of toilet paper while being rotated. The noise factor becomes and embarrassing irritant to the user when dispensing from a recessed fixture located in an interior wood frame/sheet rock wall assembly; many or these assemblies sound like sounding boards.

The flexible foamed polymer member self-aligns and snuggly holds a misshaped or uniform roll of toilet paper in place which: prevents axial play; mutilation of the paper edges; prevents paper runaway by producing a slight drag during rotation of a roll.

The device of the invention is simple in construction, efficient and time saving in operation, and lends itself to convenient and economical manufacture.

While the foregoing specification embodiments of the invention have been described in considerable detail for purposes of making a complete disclosure thereof, it will be apparent to those skilled in the art that numerous changes may be made in such details without departing from the spirit and principles of the invention.

The aforementioned information with other objects of the present invention will be described in greater detail in the remainder of the specification referring to the drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1

To achieve substantial sound reduction and paper control, paper holder is comprised of telescoped

hollow cylinder members

10 and 20 encircled by foamed polymer tube 30;

cylinder members

10 and 20 are closed on their

outside ends

14 and 24 to support

cylindrical pintles

11 and 21; the circumferential surface of

pintles

11 and 21 are encircled with

felt strips

12 and 22, and the ends of

pintles

11 and 21 are provided with

felt disks

13 and 23.

Referring to FIG. 2

So that the insertion of a full roll of toilet paper may be accomplished with equal ease and quickness, foamed polymer tube 30 has been made shorter than the length of a standard toilet paper core 40, enabling the fingers of ones hand to be inserted at either end of the toilet paper holder, in the space between either cylinder member 10 and polymer tube 30, or the space between cylinder member 20 and polymer tube 30; the larger space 60 between cylinder member 20 and polymer tube 30 allows a slight tilting of the

nested cylinder members

10 and 20.

Flexible foamed polymer tube 30

encircles cylinder members

10 and 20. Tube 30 is adhered to cylinder member 10. Cylinder member 20 is slidable through polymer tube 30 and the open inside end 10A and is telescopically nested within cylinder member 10. The inside end 20A of cylinder member 20 is partially closed to restrain helical compression spring 50, mounted between the outside end of cylinder member 10 and the inside end of cylinder member 20. Spring 50 exerts a longitudinal force, which urges both

cylinders

10 and 20 to extend axially.

To prevent the telescoped cylinder members from pulling apart cylinder member 10 is provided with an internal ridge 10B and cylinder member 20 is provided with and external ridge 20B.

Referring to FIG. 3

An end view 14 of cylinder member 10, showing end views of polymer tube 30, pintle 11 and felt disk 13.

Referring to FIG. 4

An end view 24 of cylinder member 20, showing end views of polymer tube 30, pintle 21, felt disk 23 and space 60 between cylinder member 20 and polymer tube 30.

Referring to FIG. 5

Cylinder members

10 and 20 are shown with an internal annular ridge 10B and external annular ridge 20B, respectively. The ridges 10B and 20B prevent

cylinder members

10 and 20 from coming apart.
